Save image to sdcard from drawable resource on Android

Save image to sdcard from drawable resource on Android - android

I'm wondering how to save an image to user's sdcard through a button click.
Could some one show me how to do it. The Image is in .png format and it is stored in the drawable directory. I want to program a button to save that image to the user's sdcard.

The process of saving a file (which is image in your case) is described here: save-file-to-sd-card
Saving image to sdcard from drawble resource:
Say you have an image namely ic_launcher in your drawable. Then get a bitmap object from this image like:
Bitmap bm = BitmapFactory.decodeResource( getResources(), R.drawable.ic_launcher);
The path to SD Card can be retrieved using:
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
Then save to sdcard on button click using:
File file = new File(extStorageDirectory, "ic_launcher.PNG");
FileOutputStream outStream = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
Don't forget to add android.permission.WRITE_EXTERNAL_STORAGE permission.
Here is the modified file for saving from drawable: SaveToSd
, a complete sample project: SaveImage

I think there are no real solution on that question, the only way to do that is copy and launch from sd_card cache dir like this:
Bitmap bm = BitmapFactory.decodeResource(getResources(), resourceId);
File f = new File(getExternalCacheDir()+"/image.png");
try {
FileOutputStream outStream = new FileOutputStream(f);
bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (Exception e) { throw new RuntimeException(e); }
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(f), "image/png");
startActivity(intent);
// NOT WORKING SOLUTION
// Uri path = Uri.parse("android.resource://" + getPackageName() + "/" + resourceId);
// Intent intent = new Intent();
// intent.setAction(android.content.Intent.ACTION_VIEW);
// intent.setDataAndType(path, "image/png");
// startActivity(intent);

If you use Kotlin, you can do like this:
val mDrawable: Drawable? = baseContext.getDrawable(id)
val mbitmap = (mDrawable as BitmapDrawable).bitmap
val mfile = File(externalCacheDir, "myimage.PNG")
try {
val outStream = FileOutputStream(mfile)
mbitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream)
outStream.flush()
outStream.close()
} catch (e: Exception) {
throw RuntimeException(e)
}

How to share images that are not stored on device?

I have a application where i convert the text coming from user into a QR code and display the QR code in imageView. My problem is how can i use sharing Intent on this image as their no path specified for it nor the image is stored anywhere ?

You can do it by saving the bitmap of image in cache followed by sharing it.
//To get the bitmap from Imageview
imageView.setDrawingCacheEnabled(true);
Bitmap bitmap = imageView.getDrawingCache();
//To share it via Intent**
try {
File file = new File(getContext().getCacheDir(), fileName + ".png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}

Saving a bitmap file in android and reading back to display in Imageview

I have a bitmap file which i need to upload to my php server but as the file is very large I decided to resize it and save it. Later on I try to read it back to display resized image. But this time I am not getting the same image
Below is code for writing image and returning File
public static File savebitmap(Bitmap bmp) throws IOException {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "testimage.jpg");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
return f;
}
Below is code for reading and displaying
File file=ImageUtil.savebitmap(this.bitmap);
this.imgChoosenImage.setImageURI(Uri.parse(file.getAbsolutePath()));
Please tell me what exactly is going wrong here

first check the images are saved in ur path as defined, and Make sure ur giving correct path for retriving image.
I have used this below code for saving imge in gallery
String iconsStoragePath = Environment.getExternalStorageDirectory()+ File.separator;
File sdIconStorageDir = new File(iconsStoragePath);
//create storage directories, if they don't exist
sdIconStorageDir.mkdirs();
try {
String filePath = null;
filePath = Environment.getExternalStorageDirectory() + File.separator + "testimage" + ".jpg";
FileOutputStream fileOutputStream = new FileOutputStream(filePath);
BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
bmp.compress(Bitmap.CompressFormat.JPG, 100, bos);
bos.flush();
bos.close();
} catch (IOException e) {
Log.w("TAG", "Error saving image file: " + e.getMessage());
Toast.makeText(getApplicationContext(), "Failed to Create folder",
Toast.LENGTH_SHORT).show();
}
For bitmap display in imageview :
File imgFile = new File("/sdcard/Images/testimage.jpg");
//Here File file = ur file path
if(imgFile.exists())
{
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
Permissions:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Unable to store Image into internal storage directory

I wanted to create a folder and store image into the phone's internal storage. I tried using the code below to download an image from the url. It managed to load the image into imageView but unable to store and create folder in the internal storage. Plus I got no warning or error message. Any idea what's wrong code below?
Bitmap bm = null;
InputStream in;
try{
in = new java.net.URL("http://blogs.computerworld.com/sites/computerworld.com/files/u177/google-nexus-4.jpg").openStream();
bm = BitmapFactory.decodeStream(new PatchInputStream(in));
File mydir = this.getDir("mydir", Context.MODE_PRIVATE);
mydir.mkdirs();
File fileWithinMyDir = new File(mydir, "myfile");
FileOutputStream out = new FileOutputStream(fileWithinMyDir);
bm.compress(Bitmap.CompressFormat.JPEG, 85, out);
}
catch(Exception e1){
e1.printStackTrace();
}
ImageView img = (ImageView) findViewById(R.id.image_display);
img.setImageBitmap(bm);

once you have your bitmap bm:
FileOutputStream fos;
try {
fos = openFileOutput("file_Name", Context.MODE_PRIVATE);
bm.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.close();
}catch (Exception e){
...
}
will save your file to internal storage

use the following:
String path=Environment.getExternalStorageDirectory()
.toString() + File.separator
to get the directory and save the image.

Crop image from URL

I have the following:
A very long URL of where the image is located (on the internet)
String imageAddress = data.getExtras().get("imageHTTP").toString();
The returns fine and there is an image ending with .jpg
The next part is where I'm having problems.
Basically I've got a crop intent that accepts Uri's but the following doesn't work:
Uri imageUri = Uri.parse(imageAddress);
Intent intent = new Intent(this, com.android.camera.CropImage.class);
intent.setData(uri);
intent.putExtra("return-data", true);
startActivityForResult(intent, CROP);
Any ideas?
Following error code:
got exception decoding bitmap
java.lang.NullPointerException
at com.android.camera.Util.makeInputStream(Util.java:337)

I figured this out. Was easier to save it to sdcard temporary then crop, then delete the temporary one. After that I ran it though a downloaded crop library (don't know where downloaded it from but there are a few).
File file = null;
try {
URL myImageURL = new URL(imagePath);
HttpURLConnection connection = (HttpURLConnection)myImageURL.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
// Get the bitmap
Bitmap myBitmap = BitmapFactory.decodeStream(input);
// Save the bitmap to the file
String path = Environment.getExternalStorageDirectory().toString() + "/polygonattraction/app/";
OutputStream fOut = null;
file = new File(path, "temp.png");
fOut = new FileOutputStream(file);
myBitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
}
catch (IOException e) {}
Log.w("tttt", "got bitmap");
Uri uri = Uri.fromFile(file);

Save bitmap to location

I am working on a function to download an image from a web server, display it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice?
My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a FileOutputStream to write the data.
The other option I have is to use MediaStore :
MediaStore.Images.Media.insertImage(getContentResolver(), bm,
barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image");
Which works fine to save to SD card, but does not allow you to customize the folder.

try (FileOutputStream out = new FileOutputStream(filename)) {
bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (IOException e) {
e.printStackTrace();
}

You should use the Bitmap.compress() method to save a Bitmap as a file. It will compress (if the format used allows it) your picture and push it into an OutputStream.
Here is an example of a Bitmap instance obtained through getImageBitmap(myurl) that can be compressed as a JPEG with a compression rate of 85% :
// Assume block needs to be inside a Try/Catch block.
String path = Environment.getExternalStorageDirectory().toString();
OutputStream fOut = null;
Integer counter = 0;
File file = new File(path, "FitnessGirl"+counter+".jpg"); // the File to save , append increasing numeric counter to prevent files from getting overwritten.
fOut = new FileOutputStream(file);
Bitmap pictureBitmap = getImageBitmap(myurl); // obtaining the Bitmap
pictureBitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut); // saving the Bitmap to a file compressed as a JPEG with 85% compression rate
fOut.flush(); // Not really required
fOut.close(); // do not forget to close the stream
MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());

outStream = new FileOutputStream(file);
will throw exception without permission in AndroidManifest.xml (at least in os2.2):
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Inside onActivityResult:
String filename = "pippo.png";
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, filename);
Bitmap bitmap = (Bitmap)data.getExtras().get("data");
try {
FileOutputStream out = new FileOutputStream(dest);
bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}

Some formats, like PNG which is lossless, will ignore the quality setting.

Here is the sample code for saving bitmap to file :
public static File savebitmap(Bitmap bmp) throws IOException {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 60, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "testimage.jpg");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
return f;
}
Now call this function to save the bitmap to internal memory.
File newfile = savebitmap(bitmap);
I hope it will help you.
Happy codeing life.

I know this question is old, but now we can achieve the same result without WRITE_EXTERNAL_STORAGE permission. Instead of we can use File provider.
private fun storeBitmap(bitmap: Bitmap, file: File){
requireContext().getUriForFile(file)?.run {
requireContext().contentResolver.openOutputStream(this)?.run {
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, this)
close()
}
}
}
How to retrieve file from provider ?
fun Context.getUriForFile(file: File): Uri? {
return FileProvider.getUriForFile(
this,
"$packageName.fileprovider",
file
)
}
Also do not forget register your provider in Android manifest
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>

Why not call the Bitmap.compress method with 100 (which sounds like it is lossless)?

Bitmap bbicon;
bbicon=BitmapFactory.decodeResource(getResources(),R.drawable.bannerd10);
//ByteArrayOutputStream baosicon = new ByteArrayOutputStream();
//bbicon.compress(Bitmap.CompressFormat.PNG,0, baosicon);
//bicon=baosicon.toByteArray();
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
OutputStream outStream = null;
File file = new File(extStorageDirectory, "er.PNG");
try {
outStream = new FileOutputStream(file);
bbicon.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch(Exception e) {
}

I would also like to save a picture. But my problem(?) is that I want to save it from a bitmap that ive drawed.
I made it like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.save_sign:
myView.save();
break;
}
return false;
}
public void save() {
String filename;
Date date = new Date(0);
SimpleDateFormat sdf = new SimpleDateFormat ("yyyyMMddHHmmss");
filename = sdf.format(date);
try{
String path = Environment.getExternalStorageDirectory().toString();
OutputStream fOut = null;
File file = new File(path, "/DCIM/Signatures/"+filename+".jpg");
fOut = new FileOutputStream(file);
mBitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
MediaStore.Images.Media.insertImage(getContentResolver()
,file.getAbsolutePath(),file.getName(),file.getName());
}catch (Exception e) {
e.printStackTrace();
}
}

The way I found to send PNG and transparency.
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
"/CustomDir";
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
String format = new SimpleDateFormat("yyyyMMddHHmmss",
java.util.Locale.getDefault()).format(new Date());
File file = new File(dir, format + ".png");
FileOutputStream fOut;
try {
fOut = new FileOutputStream(file);
yourbitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
Uri uri = Uri.fromFile(file);
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "");
intent.putExtra(android.content.Intent.EXTRA_TEXT, "");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent,"Sharing something")));

You want to save Bitmap to Directory of your Choice. I have made a library ImageWorker that enables the user to load, save and convert bitmaps/drawables/base64 images.
Min SDK - 14
Pre-requisite
Saving files would require WRITE_EXTERNAL_STORAGE permission.
Retrieving files would require READ_EXTERNAL_STORAGE permission.
Saving Bitmap/Drawable/Base64
ImageWorker.to(context).
directory("ImageWorker").
subDirectory("SubDirectory").
setFileName("Image").
withExtension(Extension.PNG).
save(sourceBitmap,85)
Loading Bitmap
val bitmap: Bitmap? = ImageWorker.from(context).
directory("ImageWorker").
subDirectory("SubDirectory").
setFileName("Image").
withExtension(Extension.PNG).
load()
Implementation
Add Dependencies
In Project Level Gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
In Application Level Gradle
dependencies {
implementation 'com.github.ihimanshurawat:ImageWorker:0.51'
}
You can read more on https://github.com/ihimanshurawat/ImageWorker/blob/master/README.md

Make sure the directory is created before you call bitmap.compress:
new File(FileName.substring(0,FileName.lastIndexOf("/"))).mkdirs();

Create a video thumbnail for a video. It may return null if the video is corrupted or the format is not supported.
private void makeVideoPreview() {
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(videoAbsolutePath, MediaStore.Images.Thumbnails.MINI_KIND);
saveImage(thumbnail);
}
To Save your bitmap in sdcard use the following code
Store Image
private void storeImage(Bitmap image) {
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
Log.d(TAG,
"Error creating media file, check storage permissions: ");// e.getMessage());
return;
}
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
image.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
} catch (FileNotFoundException e) {
Log.d(TAG, "File not found: " + e.getMessage());
} catch (IOException e) {
Log.d(TAG, "Error accessing file: " + e.getMessage());
}
}
To Get the Path for Image Storage
/** Create a File for saving an image or video */
private File getOutputMediaFile(){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
+ "/Android/data/"
+ getApplicationContext().getPackageName()
+ "/Files");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
File mediaFile;
String mImageName="MI_"+ timeStamp +".jpg";
mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);
return mediaFile;
}

Some new devices don't save bitmap So I explained a little more..
make sure you have added below Permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and create a xml file under xml folder name provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external_files"
path="." />
</paths>
and in AndroidManifest under
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
then simply call saveBitmapFile(passYourBitmapHere)
public static void saveBitmapFile(Bitmap bitmap) throws IOException {
File mediaFile = getOutputMediaFile();
FileOutputStream fileOutputStream = new FileOutputStream(mediaFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, getQualityNumber(bitmap), fileOutputStream);
fileOutputStream.flush();
fileOutputStream.close();
}
where
File getOutputMediaFile() {
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory(),
"easyTouchPro");
if (mediaStorageDir.isDirectory()) {
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(Calendar.getInstance().getTime());
String mCurrentPath = mediaStorageDir.getPath() + File.separator
+ "IMG_" + timeStamp + ".jpg";
File mediaFile = new File(mCurrentPath);
return mediaFile;
} else { /// error handling for PIE devices..
mediaStorageDir.delete();
mediaStorageDir.mkdirs();
galleryAddPic(mediaStorageDir);
return (getOutputMediaFile());
}
}
and other methods
public static int getQualityNumber(Bitmap bitmap) {
int size = bitmap.getByteCount();
int percentage = 0;
if (size > 500000 && size <= 800000) {
percentage = 15;
} else if (size > 800000 && size <= 1000000) {
percentage = 20;
} else if (size > 1000000 && size <= 1500000) {
percentage = 25;
} else if (size > 1500000 && size <= 2500000) {
percentage = 27;
} else if (size > 2500000 && size <= 3500000) {
percentage = 30;
} else if (size > 3500000 && size <= 4000000) {
percentage = 40;
} else if (size > 4000000 && size <= 5000000) {
percentage = 50;
} else if (size > 5000000) {
percentage = 75;
}
return percentage;
}
and
void galleryAddPic(File f) {
Intent mediaScanIntent = new Intent(
"android.intent.action.MEDIA_SCANNER_SCAN_FILE");
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}

Hey just give the name to .bmp
Do this:
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.PNG, 40, bytes);
//you can create a new file name "test.BMP" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "**test.bmp**")
it'll sound that IM JUST FOOLING AROUND but try it once it'll get saved in bmp foramt..Cheers

After Android 4.4 Kitkat, and as of 2017 share of Android 4.4 and less is about 20% and decreasing, it's not possible to save to SD card using File class and getExternalStorageDirectory() method. This method returns your device internal memory and images save visible to every app. You can also save images only private to your app and to be deleted when user deletes your app with openFileOutput() method.
Starting with Android 6.0, you can format your SD card as an internal memory but only private to your device.(If you format SD car as internal memory, only your device can access or see it's contents) You can save to that SD card using other answers but if you want to use a removable SD card you should read my answer below.
You should use Storage Access Framework to get uri to folder onActivityResult method of activity to get folder selected by user, and add retreive persistiable permission to be able to access folder after user restarts the device.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
// selectDirectory() invoked
if (requestCode == REQUEST_FOLDER_ACCESS) {
if (data.getData() != null) {
Uri treeUri = data.getData();
tvSAF.setText("Dir: " + data.getData().toString());
currentFolder = treeUri.toString();
saveCurrentFolderToPrefs();
// grantUriPermission(getPackageName(), treeUri,
// Intent.FLAG_GRANT_READ_URI_PERMISSION |
// Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
final int takeFlags = data.getFlags()
& (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
// Check for the freshest data.
getContentResolver().takePersistableUriPermission(treeUri, takeFlags);
}
}
}
}
Now, save save folder to shared preferences not to ask user to select folder every time you want to save an image.
You should use DocumentFile class to save your image, not File or ParcelFileDescriptor, for more info you can check this thread for saving image to SD card with compress(CompressFormat.JPEG, 100, out); method and DocumentFile classes.
